First impressions:

1. The data in most of the plots (see the appendix) look fake. Real life data does not look that clean.

2. In May of 2022, 6 months before chatGPT put genAI in the spotlight, how does a second-year PhD student manage to convince a large materials lab firm to conduct an experiment with over 1,000 of its employees? What was the model used? It only says GANs+diffusion. Most of the technical details are just high-level general explanations of what these concepts are, nothing specific.

"Following a short pilot program, the lab began a large-scale rollout of the model in May of 2022." Anyone who has worked at a large company knows -- this just does not happen.

FWIW, in the q&a after a talk, he claims that it was a GNN (graph neural network), not a GAN.

(In this q&a, the audience does not really question the validity of the research.)

Oh interesting. I haven't talked to any recent graduates but I would expect an MIT PhD student to be more articulate and not say "like" every other word.

There was a question at the end that made him a little uncomfortable:

[1:00:20]

   Q: Did you use academic labs only or did you use private labs?

   A: (uncomfortable pause) Oh private, yeah, so like all corporate, yeah...

   Q: So, no academic labs?

   A: I think it's a good question (scratches head uncomfortably, seemingly trying to hide), what this would look like in an academic setting, cause like, ... the goals are driven by what product we're going make ... academia is all, like "we're looking around trying to create cool stuff"...
My 8 year-old is more articulated than this person. Perhaps they are just nervous, I'll give them that I guess.

Using the word "like" is not as bad as it seems, and it's been quite common in language for longer than we think (though usage does seem to increase with each generation).

There was a recent podcast that covered it with some experts that's a great listen:

When you use it as a comma, it’s bad.

The word has many, many uses: filler/pause, oral punctuation, discourse marker, hedging, qualifier. It also serves an important social function, in that it can reduce perceived severity or seriousness. Young women seem to use it assure peers that they are sweet and not threatening.

I hate it. It's not uncommon to hear it more than four or five times in a single sentence.

The implied expectations are odious: eloquence is a faux pas; directness is rude; a fifth-grade vocabulary is welcoming.

That's just, like, your opinion.
